 Use signals (already in `GameState`) for UI updates instead of polling or cross-node direct mutation.
 No Cursor/Claude/Windsurf/Cline/Goose/Copilot rule files were found in this repository, so this file is the canonical agent guidance.
 Avoid trivial one-line wrapper/helper functions that only forward or repack data. Inline the logic at the real call site unless the wrapper adds meaningful abstraction or is reused enough to justify it.
+Resource type safety: Use the specific resource. Avoid as much as possible explicit `Resource` usage.
